Water Bottle Label Changeover Planning
Why can a wider label pitch shorten roll autonomy?
"These are invented teaching inputs, not equipment ratings, market prices or an accepted tolerance. The two scenarios change one assumption while holding the other inputs constant. Use the comparison to identify what must be measured or agreed for your project."
Two planning scenarios
Record item,Unit,Scenario A,Scenario B,How to establish this input
Remaining label web length,m,450,450,"Use the applicable drawing revision or an actual dimension record, with the stated unit. Identify internal, external, usable or clearance dimensions explicitly. A nominal catalogue dimension does not establish the installed usable space."
Label pitch,mm,180,220,"Use the applicable drawing revision or an actual dimension record, with the stated unit. Identify internal, external, usable or clearance dimensions explicitly. A nominal catalogue dimension does not establish the installed usable space."
Bottle rate,Bottles/h,7200,7200,"Record the quantity or distance and the corresponding observation time, named product format and operating mode. Distinguish a measured rate from a quoted capability; an average across a different window is not the same input."

What the comparison means,"Web length and bottle rate stay fixed while the label pitch increases. Fewer complete labels fit on the remaining roll, reducing nominal run time. Use actual pitch, including the gap, rather than printed artwork length. Splice material and rejected labels should be excluded from useful stock when preparing the replenishment plan."
Evidence to request,"Check usable web length, repeat pitch, roll-change practice, splice losses and reject records for the named label format. Compare the result with the operator’s observed replenishment window."
Input assumptions,"Identify the bottle, pack or material configuration, operating mode and measurement boundary. State the start and finish of the observation and which accepted output the comparison represents; unlike boundaries cannot establish a performance improvement."
How to establish this input,"Mark every input as measured, taken from a drawing, quoted or assumed. Retain the source document identifier, revision, date and responsible person. The same numeral with a different unit or data status is not automatically a comparable input."
Project decision record,Ask the responsible supplier and buyer to agree actual acceptance criteria and the evidence that will demonstrate them. Teaching values and calculated outputs on this page do not become approved operating settings or contractual performance guarantees.
Evidence to request,"Record the decision affected by the result, the measurement or trial still needed, its owner and the next review. Keep unresolved items visible in the handover file instead of changing the figures to make a preferred equipment option appear acceptable."
